Article
Apioideae is the biggest and the most diverse of four subfamilies recognised within Apiaceae. Except for a few, likely derived, woody clades, most representatives of this subfamily are herbaceous. In the present study, we assessed stem anatomy of 87, mostly therophytic and hemicryptophytic, species from at least 20 distinct lineages of Apioideae, a...

Premise Despite intensive research, the pathways and driving forces behind the evolution of derived woodiness on oceanic islands remain obscure. The genus Daucus comprises mostly herbs (therophytes, hemicryptophytes) with few rosette treelets (chamaephytes) endemic to various Macaronesian archipelagos, suggesting their independent evolution. To el...

Although the subfamily Apioideae (Apiaceae) comprises mostly herbaceous species, woody habit occurs in several clades. Character mapping on molecular tree suggests that all these woody taxa are derived from herbaceous ancestors, i.e., they represent secondary woodiness. According to Carlquist's theory of paedomorphosis, their mature wood should exh...

Conference Paper
Full-text available
Common ancestor of angiosperms was most probably woody; therefore, extant woody species may have originated through the retention of woody habit (primary woodiness) or through its loss (herbaceous stage) and subsequent re-evolution (secondary woodiness). According to Dollo’s principle of irreversibility, a trait once lost cannot be regained in an u...

Umbellifer tribe Daucinae comprises mostly herbaceous species with the notable exception of few rosette treelets, recently transferred to the carrot genus (Daucus): Daucus decipiens (= Melanoselinum decipiens), D. edulis (= Monizia edulis), D. elegans (= Cryptotaenia elegans), and some species formerly placed in Tornabenea. Character mapping on mol...

Annual, biennial or perennial, monocarpic or polycarpic, caulescent or acaulescent, glabrous or pubescent or glandular-pubescent herbs, rarely suffrutescent or woody subshrubs, shrubs or trees, evergreen or deciduous; with taproots, rhizomes, or unbranched to branched rootstocks, sometimes swollen and tuberiform; with schizogenous secretory canals...
Article
If in France, genetic resources of cultivated carrot are well studied and preserved, the wild compartment of the species remains less known and underutilized, while there are many populations of wild carrot on the French territory. Several collecting missions were undertaken from 2009 to 2014 to identify and collect populations, particularly in coa...

Scandiceae subtribe Daucinae encompasses umbellifers that have fruits with prominent secondary ridges projecting into wings (former tribe Laserpitieae) or spines (former tribe Caucalideae pro parte). It comprises several economically or medicinally important genera including Cuminum, Daucus, Laser, Laserpitium and Thapsia among others. Recent molec...

Etablir une Liste rouge vise à dresser un bilan du degré de menace pesant sur les espèces à l’échelle d’un territoire donné. L’objectif est de mesurer le risque de disparition des espèces qui s’y reproduisent en milieu naturel ou qui y sont régulièrement présentes. La première Liste rouge des plantes vasculaires d’Alsace avait été établie par la So...

A morphological study of a new species of Apiaceae and a molecular systematic analysis based on ITS sequences has led to the description of the new genus Pseudoridolfia that is related to Foeniculum, Ridolfia and Anethum. The new species, P. fennanei, occurs in the Tetraclinis articulata formations of the semi—arid valleys located on the northern f...

In Lebanon, Coriandrum sativum L., Eryngium creticum Lam., Foeniculum vulgare Mill., Petroselinum crispum (Mill.) Fuss are cultivated and gathered for their nutritional and medicinal properties. Fine pollinic morphology was studied for four samples taken out of each of the four species, in order for attempting to highlight distinctive characters in...

In Lebanon, three Rosaceae from Pyreae tribe are commonly cultivated: Pyrus syriaca Boiss., Crataegus azarolus L., C. monogyna Jacq. Four samples were taken on the flowers of three species to study the pollinic morphology with light and scanning electron microscope. The morphologic observation and the numerical treatment of various types of charact...

The aim of the monograph of the Umbelliferae of France was to take stock of the knowledge of all the species (indigenous or naturalized) extant in that country. It required a pluridisciplinary approach which led to a long-term study resulting in a five-volume work. This long work allows for comparisons of genera within the family and may lead to a...
